WlCK-ADJUSTING, DEVICE FOR LAM PS.

SPECIFICATION forming part of Letters Patent No. 623,931, dated April 25, 1899.

Application filed April 23, 1898.

To ail whom it may concern.-

Be it known that 1, WILLIAM H. STIMPsoN, of Vinthrop, in the county of Suffolk and State of Massachusetts, have invented an 1m provement in Wick-Adjusting Devices for Lamps, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

This invention has for its object the production of a novel and simple wick-adjuster for oil-lamps particularly adapted for use in connection with a lamp of the type shown in United States Patent No. 545,313, granted August 27, 1895.

I have herein shown and described my invention as applied to a lamp such as shown in the patent referred to, though my invention is not necessarily limited thereto.

Figure 1 represents in vertical section a lamp provided with a wick-adjuster embodying my invention. Fig. 2 is a front elevation of the Wick-adj uster applied to the end of a wick-tube; and Fig. 3 is an enlarged transverse sectional view of the wick-adjuster on the line a: 0:, Fig. 1.

Referring to Fig. 1, the oil-reservoir A, the neck supporting the bulb c of the wick-tube c and having at its top the burner c, the wick f within the tube and terminating at the burner, and the outer globe or shade Z) are and may be all substantially as shown and described in the patent referred to.

My wick-adj uster (shown separately in Fig. 2) comprises an expansible body portion d, made herein as a longitudinally-slotted cylinder, preferably of metal, connected by a neck d with a substantially tubular wickguide (Z the latter having laterally-extended parallel ears (1- on the side opposite the neck d. The wall of the wick-guide d is preferably flattened at 6. below the neck, as clearly shown in Fig. 3, and opposite this flattened portion the wick-actuator is located, shown as a spur-wheel or sharply-notched disk d mounted between the ears d to rotate on a pin 0.

Referring to Fig. 3, it will be seen that the space between the flat wall d of the wickguide and the periphery of the spur-wheel is Serial No. 678,553. (No model.)

quite small, to thereby insure at all times the engagement of the spur-wheel with the wick, the flattened part of the wick-guide providingasupport for the wick against the thrust of the controlling-wheel (V.

The body d of the device is adapted to be sprung upon the lower end of the wick-tube as shown in Figs. 1 and 2, whereon it is firmly held by frictional engagement, one or more inturned lugs or stops 3 on the inner end of the body engaging the end of the wicktnbe and preventing the body from being pushed far enough upon the wick-tube to bring the latter into engagement with the wick-actuator d The wick-guide d guides the wick along into engagement with the actuator d whence the wick passes along the neck (1 into the end of the wick-tube.

In order to adjust the wick, the wick-tube is lifted from the reservoir, and a light touch of the finger on the exposed periphery of the actuator will operate to raise or lower the wick as desired.

By reason of the resiliency of the body d the wick-adjusting device is readily applied to the wick-tube and is firmly held in place thereon.

The connection of the wick-guide and body by the narrow neck d permits free access of oil to the wick between the actuator and the end of the wick-tube and also serves to maintain the support for the actuator sufficiently separated from the body and the end of the Wick-tube to permit perfect operation of the actuator.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A wick-adj usting device comprising a body portion, a limiting-stop thereon, a connected wick-guide, and a rotatable wick-actuator mounted on and to enter the guide to of the actuator being exteriorly exposed to be engaged by the fingers, to operate, substantially as described.

2. A wick-adjusting device comprising an expansible attaching-body, an adjacent tubular wick-guide having integral lateral ears and its walls flattened interiorly between said engage the wick, a portion ofthe periphery cars, and a spur-wheel rotatably mounted betion to engage the wick between the flattened tween the ears to enter the wick-guide beportion of the guide and the periphery of the tween them to engage the wick between the actuator, substantially as described.
